Name
Endotricha dentiprocessa Li sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype ♂ – China, Guangxi Zhuang Autonomous Region: Qinmu Village, Yongfu County (24°59'N, 109°59'E), 160 m, 5.V.2008, coll. Li Zhang and Hui Zhen, genitalia slide no. SYL11029. Paratypes: 1 ♂, 2 ♀, same data as for holotype except dated 1−5.V.2008.
Diagnosis
This species is superficially similar to Endotricha costaemaculalis Christoph, 1881, but can be distinguished in the male genitalia by the valva having the basal 1/4 ventrally dentate and the sacculus being distally produced into a stout thumb-shaped process, and in the female genitalia by the corpus bursae having basal half wider than distal half. In Endotricha costaemaculalis, the valva is not dentate ventrobasally, the sacculus process is narrowing to a point; and the basal half of the corpus bursae is narrower than the distal half.
Description
Adult (Fig. 1): Wing expanse 17.0−18.5 mm. Head blackish brown. Antenna yellowish brown, scape grayish white dorsoapically, flagellum with blackish brown dorsal annuli. Labial palpus blackish brown except second and third segments grayish-white at apices. Thorax and tegula dark yellowish brown. Forewing blackish brown, covered with dense reddish brown scales; costal margin black, interrupted with white dots, with a large ill-defined yellow spot before subterminal line; antemedian line white, slightly arched outward; discal spot inconspicuous; subterminal line purplish red, discontinuous, edged with black; terminal line black, edged with a broad purplish red band along inner margin; fringe reddish brown mottled black at apex, from below apex to anterior 1/4 of termen creamy white, from anterior 1/4 to tornus black mottled purplish red, blackish grey mottled reddish brown on dorsal margin, with a white basal line. Hindwing concolorous to forewing, yellowish white on costal margin; antemedian line white; postmedian line grayish white, edged with black, sinuate; terminal line black; fringe blackish grey mottled purplish-red and white along termen, grayish white on apex and along dorsal margin. Legs pale yellow on dorsal surface, blackish brown on ventral surface; tarsi with brown rings.
Male genitalia (Fig. 9). Uncus inverted triangular, caudal margin gently arched, concave at middle, extending outwards posterolaterally to pointed ends; uncus arm ear-shaped, straight, rounded apically; uncus processes triangular, with dense spines, located at about 2/5. Gnathos narrowly elongate, rounded apically, slightly shorter than arm; arm broad band-shaped. Transtilla large and broad, widened medially, narrowing outwards to both ends. Valva broad tongue-shaped, rounded at apex; costa arched medially; ventral margin concave at base, basal 1/4 with a narrow sclerotized plate bearing large teeth. Sacculus with basal 3/5 broad, with sclerotized narrow edge ventrally, distally produced to a stout thumb-shaped process, slightly hooked backward dorsoapically, reaching beyond middle length of valva apically. Vinculum short and broad; saccus short and broad, triangular. Juxta large hexagonal. Phallus slightly shorter than valva, with fine spines; ductus ejaculation from basal 1/3.
Female genitalia (Fig. 14). Ovipositor nearly triangular, narrowing posteriorly to rounded caudal margin. Apophysis posterioris long and slender, about three times length of apophysis anterioris. Ostium bursae broad, trapezoid, weakly sclerotized; antrum heavily sclerotized, funnellike, longer than half length of apophysis anterioris; ductus bursae membranous, shorter than antrum. Corpus burase large and elongate oval, basal half wider than distal half; signum small and rounded, placed at posterior 1/3.
Distribution
(Map 1). China (Guangxi).
Etymology
The specific epithet is from the Latin prefix dent-, meaning dentate, and processus, meaning process, in reference to the valva with narrow sclerotized plate bearing large teeth ventrobasally.
